Hacked Wall Clock (after Lord Vetinari)

This clock ticks erratically but still keeps accurate time. Its mechanism has been replaced by a programmable chip that emits 64 randomly spaced ticks every 64 seconds.

Jack-O'-Launchpad

Perhaps not the most imaginative used of a Tiva Launchpad, but the default application makes for a serviceable Jack-O'-Lantern. Powered by a USB adapter from CUI, a freebie via @digikey on twitter. Nice!
